MECHANISM FOR CLEANING SEWERS.

SPECIFICATIDN forming part of Letters Patent are. 382,127, dated May 1, 1888.

Application filed May 17, 1887.

T0 on whom it may concern.-

Be it known that I,- Jonn ADAMS WYMAN, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented a new and useful Mechanism for Cleaning Sewers, of which the following is a specification.

My invention relates to mechanism for removing earthy and other solid substances from sewers used for draining towns and cities, and for other purposes; and the objects of my im provements are to provide a mechanism that may be placed in the sewer and moved hori zontally therein by any suitable motor for the purpose of carrying forward any earthy matter that may collect in a sewer and deposit at or near a man-hole in said sewer, or into an elevator being so constructed and arranged that as the buckets thereof are moved in the proper direction they will take the earthy matter from the sewer and deposit it in a cart or other vehicle standing in the street; second, to provide a scoop of novel construction for collecting the earthy or other refuse matter and carrying it forward to the vicinity of the man-hole or to the elevator, and, third, to provide certain combinations for operating the scoop which collects the earthy matter and the elevator which raises it out of the sewer. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a horizontal and vertical sectional elevation showing a section of a sewer chains or ropes for moving said scoop, a movable frame supporting a Windlass which oper made adjustable, a cart for receiving the material from the elevator, and a chute for directing it into said cart. Fig. 2 is a perspective view showing a scoop made adjustable as to width in order that it may be made to fit sewers of different widths.

In Fig. l of the drawings there is shown a sewer, A, which may be of any of the forms recognized as suitable, it being provided with man holes A at suitable distances apart, which, as sewers are at present constructed, serve to admit persons to the sewer and the removal of earthy matter therefrom, which Serial No. 238.470. (No model.)

matter under the present system is bailed or shoveled into buckets, lifted out, and poured into open carts for removal to the dumping-- My invention has for its object the remedy- I ing of the above-recited and other objections to the existing method, to accomplish which I provide a scoop, B, which, when used in a cylindrical sewer, may be of the form shown in Fig. 2, where it is shown to be adjustable in one direction, in order that it may be adapted to sewers of different diameters, the adjustability being provided for by allowing the sheets of metal B B" to overlap each other, and providing them with slots,through which bolts pass for holding them in their adjusted position. In providing for placing this scoop in the sewer when its dimensions are so great as to prevent it from passing through the man holes, it is proposed to make the parts B B of sheets of such width that they can be readil passed into the sewer,where they can be bolted or riveted together.

construction and with any number of folds that may be required to give the force neces= sary to move the scoop by a Windlass turned by the hand of the operator; or it may be turned by steam or horse power. There is shown in Fig. 2 a device,B*,to which the inner end of the fold B is attached, from which point it extends to a point near a man-hole, as shown in Fig. 1, where it is secured to a block of wood or metal, 0, which is attached to the upper inner surface of the sewer by any suitable means. To the side of the block 0 which is opposite the one to which the fold B is secured there is attached a bracket, 0, the outer end of which carries a grooved sheave, over which the free end B of the fold passes, and from which it is let up through the man-hole to and around a windlass or drum, so that as the drum is revolved the scoop will be caused to move horizontally in the sewer, the effect of which will be to cause it to carry forward any earthy or other matter that may have been deposited in the sewer and place it in a position where it can be taken out by an elevator,soon to be described.

For preventing the material in the sewer from being carried past the man-hole in which the elevator is placed, there is provided a bulkhead, 0, which is by preference made of two or more parts, as shown in Fig. 1, so that it can be made to fit sewers of different diameters, and so that it can readily be taken apart when it is to be removed from the sewer.

The elevator above alluded to is clearly shown at D in Fig. 1, where it is represented as being in position for use, itslower end having been passed down through one of the manholes of a sewer, in which position it is held by the frame of the windlass or in any other convenient manner, its construction and arrangement being substantially such as is shown and as enables it to receive the material brought to it by the scoop, carryit to the desired elevation, and deliver it into a spout, D", by which it is directed intoa cart, which is by preference provided with a tight cover, in order that the offensive odors that would otherwise arise from it may be prevented from escaping. In constructing an elevator of this character I prefer to make the band to which the buckets are attached of flat links of metal andto attach the buckets thereto by rivets. This elevator may be drivenby a crank or pulley placed on the shaft D in its upper end; or it may be driven by a rope or belt, E, passed around the windlass or drum which moves the scoop, as shown in Fig. 1.

Having thus described my invention,whatI claim, anddesire to secure by Letters Patent, 1s-

1. A scoop arranged to be moved horizon tally in a sewer and to move the earthy and other deposits found therein from one point thereof to another and deposit them at difierent points for removal, in combination with an adjustable bulk'head, substantially as specified, and for the purpose set forth.

2. Thehorizontally-adjustablescoopB, made of two or more sheets of metal, provided with inwardly-projecting flanges having in them slots for permitting the sheets to be adjusted in the manner described, whereby the scoop is made capable of use in sewers of different diameters, as described.

3. In combination with a street or other sewer, a scoop for removing the earthy matter from a sewer, a bulk-head for checking the movements of the earthy matter, and suitable mechanism for imparting movement to said scoop, substantially asset forth.

4. In a mechanism for cleaning sewers, the combination of an elevator supplied with aseries of buckets for elevating the material carried forward by the scoop, and a bulk-head for arresting the movements of said material, the arrangement of the parts being substantially as described, whereby the lower end of the elevator is made capable of being inserted into a sewer. 7
